CI/CD流水线是现代软件交付的核心。不当的CI/CD配置会导致构建缓慢、部署失败和质量问题。在设计CI/CD流水线前需要仔细分析交付需求。
核心原则: 好的CI/CD流水线应该快速、可靠、自动化、可监控。坏的CI/CD流水线会导致构建瓶颈、部署风险和质量问题。
始终:
触发短语:
问题:
构建缓慢，资源浪费
错误示例:
- 缺少构建缓存
- 依赖重复下载
- 串行构建流程
- 资源配置不足
解决方案:
1. 配置构建缓存机制
2. 优化依赖管理策略
3. 实施并行构建
4. 合理分配构建资源
问题:
部署不稳定，回滚频繁
错误示例:
- 环境配置错误
- 部署脚本问题
- 健康检查缺失
- 回滚策略不当
解决方案:
1. 标准化环境配置
2. 完善部署脚本
3. 添加健康检查
4. 实施自动回滚
问题:
代码质量差，缺陷频发
错误示例:
- 测试覆盖不足
- 代码检查缺失
- 安全扫描遗漏
- 质量门禁缺失
解决方案:
1. 提升测试覆盖率
2. 集成代码检查工具
3. 添加安全扫描
4. 设置质量门禁
